A power device for a vehicle includes a plurality of batteries, a case accommodating the batteries, a blower for forcibly supplying air to the batteries accommodated in the case, thereby cooling them, and a temperature sensor for coming in contact with a surface of the battery to detect a temperature of the battery. A thermal portion for detecting the temperature of the battery of the temperature sensor includes a thermal element to be thermally coupled to the surface of the battery, and a heat insulating material having a cushioning property to be elastically compressed which serves to thermally insulate the thermal element provided on the surface of the battery from the cooling air, and the thermal element is isolated from the cooling air supplied forcibly by means of the heat insulating material having the cushioning property, thereby detecting the temperature of the battery.
